The document describes four paths through an Oracle Enterprise Manager (EM) tuning demo. The paths show different ways to access performance and tuning information for a database using the EM user interface. The demo then performs a test to insert data concurrently into a table and measures the elapsed time. Following the Automatic Database Diagnostic Monitor (ADDM) recommendations, such as increasing the redo log size, reduces the elapsed time for the test from over 14 minutes to just over 1 minute.
Oracle's Real Application Testing solution provides a cost-effective and easy-to-use solution for assessing the impact of change on production Oracle databases by capturing and replaying actual database workload and workflows. The solution provides greater business agility and reduces the risk and cost associated with change.
